i bF=Z Preface This manual describes installation, operation and preventive maintenance of yourMOPO-700 series optical parametric oscillator (OPO). The manual also containsinformation about OPO theory, options and accessories.While this manual contains an installation and alignment procedure, it isnot intended as a guide to the initial installation and set-up of your MOPO. Pleasewait for the Spectra-Physics service engineer who has been assigned this task underyour semice agreement. Allow only qualified and authorized Spectra-Physics servicepersonnel to install your laser system.The Quanta-Ray MOPO-700 series is designed for use with Quanta-RayGCR-100 and GCR-200 series of pulsed Nd:YAG lasers. This combination providescontinuously tunable radiation from 410nm to over 2000nrn. Proprietary broad-bandoptics, designed and manufactured by Spectra-Physics, mean that no mirror changeor realignment is necessary when scanning across the visible or near IR spectrum.The MOPO-700 series' tuning range can even be further extended from200nm to beyond 3000nm through nonlinear processes in the Quanta-Ray FDO-800harmonic generation system and the EWO-1 wavelength extender.The MOPO-700 is compact and easy to work with. The MOPO designincorporates two coupled OPO's, a master OPO and a power OPO. This design providesthe flexibility to easily change and upgrade the output linewidth from tens ofwave numbers to below 0.02cm-', while maintaining consistent output energies. Allunits come standard with control electronics which allow the user to set all necessaryoperating parameters. Optional RS-232 and IEEE488 interfaces allow easy connectionwith existing laboratory control and data collection systems.The MOPO series emits radiation that can permanently damage eyes andskin, ignite fires, and vaporize substances. Moreover, focussed back-reflections ofeven a small percentage of its output energy can destroy expensive internal optics.To minimize the risk of expensive repairs, injury, or death, carefully follow theseinstructions.We welcome your comments on the content and style of the manual. Thelast page is a form to aid in bringing such problems to our attention. Thank-you foryour purchase of a Spectra-Physics instrument.iii
